Dont play the lotto then, it is every individual’s duty to be aware of what they buy. You can tell these people that the odds are stacked against them but if they were willing to spend it on the lotto they will end up spending it anyway on the next person/business trying to get money from them. Like my grandmother she wastes so much money on lotto tickets despite losing overall just trying to get the next elusive 500, $1000 win. If she doesn’t spend it on them she wastes it buying useless items. Everyone has to be responsible for themselves. Inform others let them make their own choice
